Dale's tape problem sounds like one of two problems (although I can't say for
sure without seeing the equipment).
1.  The Dolby levels may not be set properly and the Dolby is mistracking.
Since Dolby systems (and especially Dolby C) are level sensitive, if the
system is not calibrated properly you will get mis-matching between the treble
boost on encode and the corresponding cut on decode.  Check to make sure the
deck is calibrated before you record each tape, since this can vary from tape
to tape (not just brand to brand).
2.  There may be some mechanical problem in your tape transport - XLII-S is a
good tape and generally not prone to dropouts - Your deck is not generally
prone to this type of problem, so I'd suggest having it checked out by a
competent service shop (I don't know where you are, but if you're in the Boston
area I'd suggest Q Audio in Cambridge, or Harveys if you're in the NYC area).
General Comment:  Yes C-60's use thicker tape than C-90's but 90's from
reputable brands (like Maxell, TDK, Fuji, BASF, 3M, Nak, Denon, this is only
a partial list) should work OK.
